Python建立socket并获取信息

 import socket, sys

 port = 80
 host = "www.baidu.com"

 print "Creating socket..."
 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 print "done"

 s.connect((host, port))
 print "OK"
 print "Connected from", s.getsockname()
 print "Connected to", s.getpeername()

可以使用getsocketname()返回本地ip地址与端口号，getpeername()返回服务器ip地址与端口号。
